Summary: Catalytic asymmetric transformation is a powerful strategy for synthesizing diverse nonracemic molecular entities. Carboxylic acids have been explored as building blocks in this area, and significant advancements have been made in the last three decades. They can act as both C- and O-nucleophiles, as well as electrophiles, in asymmetric reactions under catalytic conditions.

Summary: Folding and assembling of two-dimensional laminated materials have greatly facilitated robot fabrication, creating robots with lightweight body frames and articulated joints. Rigid-flex linkages are extensively used in micro- and macro-scale robots for complex joint motions, but may face challenges when mechanical reconfiguration is needed. A new method, called reconfigurable laminates, uses geometric reconfiguration of laminate layers to alter mechanical properties and actuate joints, offering opportunities for passive stiffness control, reconfigurable joints, and bending actuation.

Summary: This study investigates the phase transition process in CsSnI3 and FAPbI3 nanowires using in situ optical micro-spectroscopy. The results show a blueshift in the photoluminescence peak during the FAPbI3 phase transition, possibly due to lattice distortion. The lower activation energy and faster phase propagation rate in FAPbI3 provide insights into the phase transition dynamics of halide perovskite materials.

Summary: This study successfully synthesized one-dimensional potassium-intercalated molybdenum chalcogenides using a rapid microwave-assisted solid-state heating protocol, and investigated the interfacial capacitance and charge transfer dynamics during proton reduction. The research found that the size increase and electronegativity decrease of chalcogens from sulfur to tellurium significantly affect the anisotropic nucleation of these structures and specific capacitance.

Summary: 1D organic metal halide hybrids (OMHHs) exhibit promising optical properties for photodetection and lighting applications, but the governing mechanisms and surface effects are not well understood. This study investigates the optical properties of 1D C4N2H14PbBr4 through polarization-dependent time-averaged and time-resolved photoluminescence spectroscopy. The results reveal an excitation-energy-dependent anisotropic emission, which is attributed to fast surface recombination confirmed by first-principles calculations and experimental measurements.

Summary: Organic-inorganic hybrid metal halides with tunable optical band gaps and emission properties were obtained by using pyridinium derivatives as organic templating cations. Among the synthesized 1D lead bromide compounds, only (2,4-LD)PbBr3 exhibited exciton-dependent emission from intense yellow-white to weak red-white. Comparisons of its photoluminescence with its bromate and other similar structures confirmed the contribution of organic cations and self-trapped excitons to the tunable emission. Density functional theory calculations revealed a stronger interaction between organic and inorganic components in (2,4-LD)PbBr3 compared to (2-MP)PbBr3. This work emphasized the importance of organic templating cations in hybrid metal halides and the new functionalities associated with them.

Summary: We discovered a family of two-dimensional oxalate-based metal-organic frameworks (MOFs) with robust spin-polarized Dirac cones. The 2D MOFs of Ni-2(C2O4)(3) and Re-2(C2O4)(3) exhibit intrinsic Dirac spin gapless semiconductor properties, large magnetic moments, high Curie temperatures, and large perpendicular magnetic anisotropy. Furthermore, Re-2(C2O4)(3) displays a topologically nontrivial band gap resulting from spin-orbit coupling.

Summary: Edge termination is crucial for determining the properties of 2D materials. Ab initio simulations reveal a lowest-energy U-edge [ZZ(U)] reconstruction in bilayer phosphorene, reducing edge energy significantly and potentially dominating. Although ZZ(U) changes the topology of phosphorene nanoribbons, it is difficult to be identified through microscopy images. This edge reconstruction also enhances the thermal conductivity of PNR significantly compared with pristine and Klein edges.

Summary: In this study, dual ruthenium atom-doped germanium clusters (Ru2Gen) were investigated using a comprehensive genetic algorithm and density functional theory (DFT) calculation. It was found that small clusters tend to adopt an exohedral structure with a Ru dimer as the core surrounded by Ge atoms. As cluster size increases, half-encapsulated structures start to form, and clusters with 12 to 15 atoms exhibit a geometry based on a regular pentagonal prism with additional Ge atoms. Certain clusters were found to have high structural and chemical stability, and possess a magnetic moment, which is different from the reported non-magnetism of monatomic doping.
